You can visualize the data a device publishes to Litmus Edge Manager using Grafana. 

To receive the `Admin` role on Grafana Dashboards, see the *Toggle Administrator role for Grafana* *section* of [Edit a User Profile](docId\:KIJgyCJC1HGIm8mW7dVRK).

# Before You Begin

You must select the **RAW data** option for the Edge Device Data Storage setting (**Litmus Edge Manager User UI** > **Company **> **Project **> **Settings **> **Edge Device Data Storage**). See [Project Settings](docId\:hmGSXiivMvDy4K43OanRv) to learn more.
